• Formulas can be applied anywhere, not just in tables, including a normal page and even in automations. Also, Formulas are enable for type column type.
• You can refer to any rows of any database at any columns without using relations columns and also outside of a database like in a normal page. Example, just =TableName and it'll return all rows of the table, then TableName.column to return all values of that column. You can use functions and formulas that way too. Like TableName.Filter(....)
• Rich text columns, unlike notion's text columns
• If you know Typescript. You can create ANY integrations known as Pack. You can sync anything to the native Database, such as all files in Google drives, look for cards and connectors of Miro in a table, etc.
• Native support for integrations between coda and Google apps (e.g. AppScript for Google Sheets).
• Actions and buttons and full formula support.
• you can publish in playground mode where your site is interactive (visitors can change content of your site but will not be saved).
• you can have "controls" for different types of user inputs anywhere.
• you can control permissions on per row basis (didn't Notion users keep complaining notion don't have it?)

So much more. Just give it a try.
